  Preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view showing a cargo box shelf structure of a cargo collection and delivery vehicle 1 according to the present invention, and shows one of the shelf members 4 attached to the inner wall surface 3 of the cargo box 2. A plurality of pillar members 5 are provided on the inner wall surface 3 of the cargo box 2 of the luggage collection / delivery vehicle 1 so as to be separated from each other. A light and high-strength metal frame material is suitable for the column member, and an aluminum frame material having a substantially hat-shaped cross section with excellent workability as shown in FIG. 2 is suitable. The column member 5 is firmly coupled to the inner wall surface 3 of the cargo box 2 by a fixing metal fitting and a screw. A large number of circular through holes 6 are arranged in a row on both sides of the column member 5 at a predetermined interval. These holes 6 are used for attaching the shelf member 4 and attaching the support member 7 that supports the shelf member 4.

  The wall 8 constituting the packing box 2 is structured to have sufficient strength. That is, the wall 8 is integrally joined with the aggregate 9 sandwiched between the outer plate 11 and the inner plate 12, and the bending moment acting via the column member 5 by placing the load 13 on the shelf member 4. It has enough strength to withstand.

  2-7 is drawing which shows the state which attached the shelf member to the pillar member, and the structure of a shelf member. FIG. 2 is a horizontal sectional view showing a state in which the shelf member is attached to the column member, and FIG. 3 is a view taken along the line AA in FIG. 4 shows the lower surface of the shelf member, and FIG. 5 shows the upper surface of the shelf member alone. 6 is a side view of the shelf member, and FIG. 7 is an enlarged view of a portion in FIG.

  The shelf member 4 is obtained by joining a plate member 15 to the inside of an outer edge member 14 having a substantially U-shape in plan view, and is usually manufactured from a light metal material such as aluminum from the viewpoint of weight reduction. A punching hole 16 is also provided in the plate 15 which is a part on which the load is placed in order to further reduce the weight.

  Both ends of the outer edge member 14 can be detachably attached to holes on the side surfaces of the adjacent column members 5 and 5 erected on the inner wall surface 3 of the packing box 2. That is, the dimension between the both side surfaces of the outer edge member 14 is set to be slightly smaller than the distance between the side surfaces of the two adjacent column members 5, 5, and the shelf member 4 has two adjacent columns even in the horizontal state. It is dimensioned so that it can be easily inserted between the side surfaces of the members 5 and 5. A fixing pin 18 is fixed to one side surface 14 a of both side surfaces near the end of the outer edge member 14, and the outer diameter of the fixing pin 18 is in a hole 6 provided on the side surface of the column member 5. The size is such that it can be inserted. On the other hand, a movable pin 19 is attached to the other side surface 14b near the end of the outer edge member 14. As shown in FIG. 7, the movable pin 19 is a stepped round bar having a central portion in the axial direction as a large-diameter shaft 19a and small-diameter shafts 19b and 19c on both sides thereof. One of these two small-diameter shafts 19b is inserted into a hole 21 having an inner diameter slightly larger than the large-diameter shaft 19a provided in the outer edge member 14. That is, the movable pin 19 can move freely without being restrained in the axial direction with respect to the hole 21 provided in the outer edge member 14. A female screw 22 is provided on the end face of the other small-diameter shaft 19c of the movable pin 19, and a bolt 23 as a stopper for restricting movement in the axial direction is attached to the female screw 22 together with a washer 24.

  One side 25a of a substantially L-shaped bracket 25 is attached to an appropriate portion of the luggage placement plate 15 constituting the shelf member 4, and a small-diameter shaft of the movable pin 19 is attached to the other side 25b of the bracket 25. A hole 26 having a diameter slightly larger than the outer diameter of 19c is provided. A compression coil spring 27 is attached to the outside of the small-diameter shaft 19c between the end of the large-diameter portion of the movable pin 19 and the other side 25b of the bracket 25. Here, the compression allowance of the compression coil spring 27 is set to be larger than the length of one small-diameter shaft 19b, and when the movable pin 19 is moved in the axial direction in the direction of compressing the compression coil spring 27, one small-diameter shaft 19b The projecting end of the outer edge member 14 can be made substantially the same as the outer surface of the outer edge member 14. At that time, the movable pin 19 and the bolt 23 as a stopper move integrally in the axial direction, and the small-diameter shaft 19c of the movable pin 19 moves in the axial direction in the hole 26 provided in the bracket 25.

  Thus, in the present embodiment, the shelf member 4 provided with the fixed pin 18 on the one side surface 14a and the movable pin 19 on the other side surface 14b is used. Therefore, the shelf member 4 is attached to the column member 5 by first inserting the fixing pin 18 into the hole 6 on the side surface of the adjacent column member 5 and then compressing the coil spring 27 to the other column. By aligning and inserting the movable pin 19 into the hole 6 on the side surface of the member 5, it is possible to carry out the operation in an extremely short time and easily.

  In order to remove the shelf member 4 from the column member 5, first, the movable pin 19 is moved in the direction of compressing the coil spring 27 to remove it from the hole 6 on the side surface of the column member 5, and then the fixed pin 18 is removed from the other column. This can be done by removing from the hole 6 on the side of the member 5. Here, when moving the movable pin 19 in the axial direction to compress the coil spring 27, it is necessary to grip the large-diameter shaft 19a of the movable pin 19 and apply an external force. Therefore, it is preferable to provide knurled irregularities on the outer surface of the large-diameter shaft 19a to prevent sliding and to easily apply an external force.

  Next, a structure for attaching the support member 7 to the shelf member 4 will be described. Attachment shafts 28 that support the support member 7 are attached to the left and right sides of the outer edge member 14 that is substantially U-shaped in plan view. A boss portion 29 is provided at one end of the support member 7, and the support member 7 is rotatably attached to the attachment shaft 28 through a hole 31 provided in the boss portion 29. Here, the support members 7, 7 attached to the left and right sides of the outer edge member 14 are different in that they are arranged symmetrically with respect to the shelf member 4, and are common in terms of the attachment structure. Hereinafter, a structure for attaching the one support member 7 to the shelf member 4 will be described.

  The mounting shaft 28 is a simple round bar having a single diameter. One end of the mounting shaft 28 is fixed to the outer edge member 14, and the other end is fixed to the baggage placement plate member 15 via a bolt 32 and a fixing block 33. A compression coil spring 34 is mounted between the end face of the boss 29 of the support member 7 and the fixed block 33. Further, the other end of the support member 7 is provided with a locking pin 35 protruding outside the shelf member 4. Here, the compression allowance of the coil spring 34 is set to be larger than the length of the locking pin 35 protruding outward from the outer edge member 14. That is, when the support member 7 is held with one hand and an external force is applied to the coil spring 34 to compress it, the tip of the locking pin 35 can be moved to a position where it does not protrude from the side surface of the outer edge member 14. Further, when the external force applied to the coil spring 34 is released by releasing one hand holding the support member 7, the entire support member 7 is moved by the urging force of the coil spring 34. Then, the outer surface of the support member 7 comes into contact with the inner surface of the outer edge member 14. Even in this state, a predetermined compression allowance remains in the coil spring 34, and the outer surface of the support member 7 is pressed against the inner surface of the outer edge member 14 by the biasing force, and is held by a frictional force. Become. Therefore, the support member 7 does not move due to the vibration of the vehicle, and a hitting sound is not generated due to a collision with the outer edge member 14.

  Next, a structure for attaching the support member 7 to the column member 5 will be described. Here, since the mounting structure of the support member 7 to the column member 5 is also arranged symmetrically, the mounting structure of one support member 7 to the column member 5 will be described below. By inserting the fixed pin 18 and the movable pin 19 provided on the side surface of the shelf member 4 into the holes 6 on the side surfaces of the adjacent column members 5, 5, the shelf member 4 is erected on the inner wall surface 3 of the packing box 2. It can be attached to the column member 5. However, in this attached state, the shelf member 4 hangs down due to gravity and comes into contact with the inner wall surface 3. That is, the shelf member 4 is folded. When it is not necessary to place a load on the shelf, the shelf member 4 can be kept folded in this way. On the other hand, when it becomes necessary to place a load on the shelf, the shelf member 4 is rotated from the above state and lifted in the horizontal direction, and the support member 7 is attached to the column member 5 to support the shelf member 4. There is a need. Specifically, an external force is applied to the support member 7 in the direction in which the coil spring 34 is compressed, the support member 7 is rotated around the mounting shaft 28, and the locking pin 35 is inserted into the hole 6 on the side surface of the column member 5. Thus, the support member 7 can be attached to the column member 5. In this way, by inserting the locking pin 35 into the circular hole 6 on the side surface of the column member 5 and attaching the indicating member 7 to the column member 5, the load in the cargo box 2 is caught from the column member 5. Such irregularities such as notches can be eliminated, and the cargo in the cargo box 2 can be prevented from being damaged. Furthermore, these operations can be performed in a very short time and easily. Therefore, the shelf member 4 can be stored and deployed in a very short time and easily.

  In addition, the fixed pin 18 and the movable pin 19 of the shelf member 4 are inserted into the hole 6 provided in the side surface of the column member 5, and the locking pin 35 of the support member 7 is also inserted.

  In addition, when there are a wide variety of luggage sizes, it is necessary to change the vertical space between the shelves in accordance with the height of the luggage. However, in the packing box shelf structure according to the present invention, the shelf member 4 is replaced by the column member 5. Since the shelf member 4 is once removed from the column member 5, it can be easily attached to a different position. Accordingly, it is possible to efficiently load various sizes of luggage in the packing box and to load and unload the luggage in a short time.

  As mentioned above, although this invention was demonstrated based on the Example, this invention is not limited to these Examples. For example, in the above embodiment, among the both side surfaces of the shelf member 4, the fixed pin 18 is provided on one side surface and the movable pin 19 is provided on the other side surface, but the movable pin 19 may be provided on both side surfaces of the shelf member 4. . In the above embodiment, the support member 7 is disposed on the lower side of the shelf member 4. However, the support member 7 can be disposed on the upper side of the shelf member 4.
